JavaScript JavaScript and the DOM (Retiring) Responding to User Interaction Event Delegation

the event listener applies a yellow background color to the section element and its child elements when click

Not sure what my error would be here

app.js
let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  if (event.target.tagName == "INPUT") {
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
});

HI Marquis,

I see two little things. in your if statement you used "event" intstead of "e". "e" is the parameter in the call back function. I think gill used "event" in his video so that is probably why you used event :)

Also you left out the closing "}" on your if statement.

let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  if (e.target.tagName == 'INPUT') {
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
  }
});

Hope this helps. Happy coding!
